Abstract
A system and method to control establishing inter-process communications are disclosed. A message from a requesting process that is different from a serving process is received at the serving process via an inter-process communications facility. A current fingerprint of memory associated with the requesting process is determined. Whether a previously determined fingerprint is stored for the requesting process is determined where the previously determined fingerprint was determined since initialization of a processor executing the serving process. Based on a determination that the previously determined fingerprint is not stored, the current fingerprint is stored and a communications channel is established between the serving process and the requesting process. Based on a determination that the previously determined fingerprint is stored and that the previously determined fingerprint matches the current fingerprint, the communications channel is established between the serving process and the requesting process.
